"with in a day or two the ph has gone bezerk"

In hydroponics that is normal. The plant will use up nutrients and deposit back others that it does not need or use. That will change the Ph of the water and then the available nutrients are change as well.

A proper hydro grow requires you to monitor the Ph and make adjustments when needed. Most of us that means check it twice a day and adjust when you need to. Twice a day is not out of the normal. Depending on the size of your rez and how much water you hold. All the buffers are in the base GH NPK so the more nutrients you use the more buffers you have too. That does not mean to go wild on the nutrients so you have more buffers. Just know that is where they come from in the feeding process.

It's normal to adjust ph once even twice a day depending on the cycle the plant is in.

Hope you understand that.

Happy growing.
Zandor Reviewed by Zandor on . Ph issues??????? Hello, This is my first go round with hydro i have always done soiless so im kinda puzzled. Ok this setup is the living system with 3 ice clones 4 wks old. I am using the gh 3 part nutes Grow,Micro,Bloom with some added hygrozyme. When i mix my nutes i have to ph it down to 5.5-5.8 wich is fine but usually with in a day or two the ph has gone bezerk. Like sometimes the res. will say like 3.90 and the bucket will be higher like7.67 or something like huge diffrences why is this and how can i keep Rating: 5
